Abstract

目的 观察体外培养人眼脉络膜黑色素细胞的生长状况,用透射电镜、细胞免疫化学染色鉴定其性质,为进一步研究脉络膜黑色素细胞及相关眼病提供模型.方法将脉络膜组织用胰蛋白酶与胶原酶多次消化,分离得到的细胞用F12培养液进行培养、传代、冻存和复苏.用透射电镜、细胞免疫化学染色鉴定细胞性质.结果初分离的脉络膜黑色素细胞呈棕色球状体,24 h内贴壁.贴壁细胞渐变为双极、三极或树枝状,常有较长的分支,胞浆内含有棕黄色色素颗粒,传代后色素量保持稳定.电镜下可见细胞表面有少量微绒毛,胞浆内的黑素体沿胞膜分布或簇状分布.体外培养的脉络膜黑色素细胞S-100表达阳性,细胞角蛋白表达阴性.结论采用胰蛋白酶与胶原酶多次消化并在培养液中添加多种刺激因子,可建立人眼脉络膜黑色素细胞的有限细胞系。
